The man who stabbed two police officers and was then shot dead in regional South Australia spoke to the ABC more than a decade ago about his confronting experiences while working as a guard at the Woomera detention centre.
Sean Ferris was fatally shot at Crystal Brook on Wednesday, after stabbing Brevet Sergeants Ian Todd and Jordan Allely.
Sergeant Allely has since been discharged from hospital while Sergeant Todd, whose condition is critical, has shown progress following surgery on Wednesday night.
